Residual current protection

For 50 years, we have been designing complete residual current protection solutions, including protection transformers tailored to your specifications.

Since our inception, we have worked to design various RCDs. This lets us offer all our know-how so you can add a wide range of RCD protection devices to your portfolio: ultra-immunized type-A relays, type-B relays, residual current closing systems, circuit breaker and residual current protection with reconnection and measurement, and protective devices for electric vehicle chargers.
Round out your solution with passive, active transformers. We have tailor-made solutions for installations with high leakage currents and/or to provide protection in polluted environments such as substations, transformer substations and power generation systems such as wind farms.

RESIDUAL CURRENT PROTECTION

Type-A residual current protection

Solutions to ensure the safety of people and installations against any ground currents. Available with ultra-immunized system as an essential solution to avoid financial losses due to outages caused by inadvertent trips. Specially designed to protect industrial installations in AC networks (type A).

RESIDUAL CURRENT PROTECTION

Type-B residual current protection

Protective equipment designed to protect installations where there is a risk of DC current earth leakage or a combination of AC and DC current leakage.

Used as universal protection for loads such as speed or frequency drives, cold rooms, HVAC machinery, UPS and electric vehicle charging systems.

PROTECTION WITH SELF-RECLOSING

Self-reclosing circuit breaker and earth leakage protection

Wide range of solutions to guarantee personnel safety as well as maximum service continuity in the event of a ground current or breaker trip, with automatic reconnection of the installation.

ELECTRIC MOBILITY

Protection and control for electric vehicles

Solutions designed specifically to protect electric vehicle charging systems. Wide range of protection, including Type A + 6 mA DC or type B devices, with or without automatic reclosing, in compliance with the applicable laws.

PROTECTION CURRENT TRANSFORMERS

Resin-encapsulated transformers

Wide range of current transformers made with self-extinguishing resin. One of the advantages of this type of transformer is that it increases its robustness (high mechanical strength, high electrical rigidity, tropics-proof, etc.). It also makes it impossible to tamper with the transformer's core. Ideal to provide protection in polluted environments such as substations, transformer substations and power generation systems such as wind farms.

Safety

Choosing the wrong residual current protection can cause a blockage in the presence of a real leak, putting people and the components of the facility at risk, and causing spurious trips if the leakage current is below the trip threshold.
